easyest way to check if it sparks mate is to pull out the plug and connect the ht lead bk onto it , put the threaded and onto a bare bolt or the frame ( so it earths ) and kick , or pull the cord ( depending on what u got ) u should see it spark across the gap it its got one . (p.s hold it by the ht cap )
as far a checking if its got two stroke , its a tough one unless the used a coloured oil ,
imo best thing to do is empty the tank , go get some fresh petrol and add the 2 stroke urself ,
least that way u know its got some in fella ?
hope this helps
